| Description |
The durability of reinforced concrete structures significantly depends on the condition of the steel
embedded in them. Structures exposed to chloride containing environment have reduced durability due
to corrosion of the reinforcement steel. Several diffusion models have been proposed for chloride
penetration. They mainly aim at predicting the initiation of corrosion of the reinforcement. They are
based on diffusion conditions influenced by parameters such as relative humidity, temperature, rains
etc. This work presents the influence of sacrificial cathodic protection on the chloride profile in
concrete. Cathodic protection to the embedded steel in concrete was established by plugging-in a
sacrificial magnesium alloy anode at the center of the slab and providing an electrical link between
them. The current flowing between the magnesium anode and the embedded steel was regularly
measured. The water soluble chloride content at different distances from the anode and at different
times was determined after implementation of cathodic protection. The chloride content decreased at
different distances from the anode, with increase in time. The diffusion of chloride occurred at a more
accelerated rate due to the flow of cathodic protection current.
